Application filed June 8, 1907. Serial No. 377.393.

-COMB, a citizen of the United States, and

- struction.

resident of .Dobbs Ferry", in the county of Westchester and State of NewYork, have invented certain new and uscl'ul improvements in Desks, ofwhich the fOllOWlllQ' isa specification, reference being had to the.

drawings accompanying and lorming'u part of the same.

This invention relates to desks and attachments therefor, especially tothe roll-top oflice desks, by which a s ecisl table is provided ofsuitable height ihr use when a erson is standing, such table beingadapte for bookkeeping and other purposes, and adapt ed to be readilybrought into and out of operative )osition. This special table may beeither form a peri'nanent part thereof, or it may be contained in anattachment .VlliClLiS adapted to be removed from the desk.

In the accompanying drawings showing illustrative forms of thisinvention, and in which the same reference numeral refers to similarparts in the several lgurcs, Figure 1 an ordinary roll-top desk, showingmy invention applied thereto. Fig. 2 is a transverse vcrtical sectionsimilar to Fig. l shou= ing the supplemental table in operativeposition. Fig. 3 is a lront elevation of a desk equipped with myinvention, the table being shown in operative position the same as inFig.v 2. Fig.4 is a vertical section on the line 4-4 or Fig. 1 showingdetails oi. the con-- Fig. 5 is a transverse vertical tion of a modifiedl'orm, wherein the supplemental table is contained in a removablecasing. Fig. 6 is'a transverse-vcrtical section taken through the deskshowing a niodiiied form of pivoting the supports. Fig. I" is u sideelevation oi a detail.

In the illustrative embodiment oi this in- Vc-ntion shown in thedrawings, 1 an ordinary roll top desk having drawers ,2 2, pigeon holes3 8, top l, side pieces 5, cap 6, flexible cover '7 and curved S for theflexible cover when in its inoperative position, and guideways l9, l8and 9 in the side pieces 5 for the reception of lhe ends of the flexiblecover 7 when drawn out .l'rom the curved passages 8, to close and lockthe desk. 1 make a portion l0 (hereafter termed support) of each oi myside pieces 5 movable by means of a suitable hinge 11, the

uilt directly into the desk and isa transverse vertical section akenthrough other end being adapted to be held out from the side piece 5 bymeans of a pivoted leg 12 having a reduced portion 13 taking into a holelel in a plate 15, mounted on the end of the support 10. The other endof the leg 12 is pivoted at 16 within a rabbeted portion 17 of the sidepiece 5, the arrangement being such that when the support 10 is in itsinoperative position the leg 12 will lie snugly within the rabbctedportion. 17, and its top be (lush with the upper surface of the sidepiece 5, permitting the support 10 to fit snugly to the side piece 5.This support 10 has u guidewuy or grooved guide 18 (see Figs. on) whichat its upper end is forked lorming o. guideway ll) (Fig. 2) and 20 (Fig.l), the branches ol which register IOS])(- lively. with the housing 8ofthe desk, within which is mounted the flexible cover 7, and

with the housing 21, within which is mounted the flexible table .32.cover 7 and too flexible table 22 are formed of a. series ofinterlocking members 23 mounled upon a flexible backing 24 of fabric orother material, (see Figs. 1 and '3). At the extreme end of the flexibletable is prof-- crablv mounted a rigid ledge 25 which in its operativeposilion is adapted to prevent books or other objects slipping from thetable, and in its inoperative position is adapts ed lo lit up snuglyagainst the cap 6 of the desk (see Figs. 1 and 2).

When it is desired to close the desk the supplemental table being in-itsinoperative position, it is merely necessary to withdraw the flexiblecover 7 from its housing 8 in the desk, permitting its ends to pass intothe registering guii'l'wvays ilk-18 and 9, (Fig. 2), when the desk isclosed and locked in tho ordinary manner, (see Fig. 1).

ll alter opening the desk by pushing the cover 7 back into its housing 8in the desk should be desired to convert the desk into n lmok-kcepersdesk, it is merely necessary to raise each support ll) causing it tomove upon its hinge 11, and support it at the proper elevation bywithdrawing the log 13 from its seat 1'? permitting its reduced end 1'3to seat in thcholo l-l oi the plate 15, and then withdraw the flexiblesupph-unsntal table 2; from its housing 21 causing the ends of itsflexible members 23 to pass into the registering g1 iidc\i'a \,"s 20'and 18. The supplemental tublc is moved to its inoperutivc position byforcing it back into its llOUSlII 21 and unscatin the le s 12 more b l oBoth the flexible 29 to the desk and its other end 30 fastened by meansof screws or other suitable means 31 to the support 10 as shown in Figs.6 and 7. I may also instead of building the housing 21 directly mto thedesk make it in the form of a separate detachable casing 32 which may beremoved from the cap 6 of the top of the desk, (see Fig. 5).

Having thus described this invention in connection with the illustrativeembodiments thereof, to the details of which I do not desire to 'belimited, what is claimed as new-and what is desired to be secured byLetters Patent is set forth in the appended claims. a
